I have a 2003 winnebago sunova with a v10 ford triton motor I want to change the transmission filter and gasket but I need to know what type of trany my manual only says 4 speed overdrive transmission

Your transmission should be a Ford 4R100, 4 speed electronic overdrive unit.

When looking for any parts for the chassis of your motorhome you should ask for a Ford model F-53 motorhome chassis. Parts will not be listed under the coach name.

Also check the model year of your chassis, it may be an earlier year because the coach builder assigns their year once built up. The chassis might be a year or two older. May matter on some parts, not these.

Look at your VIN number for the 10th digit. 2001 = 1, 2002 = 2, 2003 = 3

I looked up a pan gasket and filter for you in Wix brand #58968.

Motorcraft (Ford) sells a filter alone as #FT-114. The original pan gasket is designed to be reusable, if it hasn't been replaced.

Excellent advice from code2e. Also, you should obtain the F53 chassis owner manual for your coach. Get it at https://www.ford.com/support/vehicle...owner-manuals/

If you're uncomfortable with getting the correct parts, take your VIN to your local Ford dealer and buy the gasket and filter directly from them.

TIP....If the pan doesn't have a drain plug.

Use an old piece of cardboard from a delivery box on the ground. As you loosen and remove the bolts, leave one bolt in the corner of the pan installed and just a few turns loose. Remove the others and the pan will drop, may need to be pried loose, and the pan will drain from that corner. Continue to loosen the one bolt and the pan will continue to drop and drain more oil in a controlled fashion.

Only use the Ford supplied pan gasket. Aftermarket fiber gaskets will normally leak. If the steel reinforced rubber gaskets is still playable it can be reused. I bought a new one anyway when I did mine.
